Automotive Sandpaper Grits for Painting a Car – Day 2 Boot Camp

Most Common Automotive Auto Body Sandpaper Grits When Painting a Car

In the video above I talk about and show you the most common automotive sandpaper grits that are used for body and paint.

These paper are used for the main body work process when cutting bondo, shaping, feathering and final sanding when prepping for paint or color sanding and buffing.

Here’s a Common Body and Paint Sandpaper Grit Rundown

Let’s start with the most coarse sandpaper grits. 32 grit. 32 grit can be used for grinding, cutting out old filler or shaping new filler if you have some extremely high areas in your bondo work. 32 grit paper can also be used for sanding heavy rusted areas.

80 grit sandpaper is the most common I think. It’s a great grit to cut and shape your body filler and sand down rusted body panels. I find myself using 80 grit a lot and I teach how and when to use it correctly.

150, 220, and 240 grit is great if you’re looking to bang out a nice single stage paint job. You know, an enamel, acrylic enamel or synthetic enamel paint job. It’s a ‘in-between” paper.

Slap a roll on your DA (dual action sander), and you’re off to the races. You can safely paint over a 240-280 grit paper. But personally, I like to get it a little smother. If I’m painting a single stage job, I get the paint down to 320 at least.

Now 150 to 280 is also used to get your 80 grit body filler smother during your body work stage in prepping for a primer that you may use.

400. I love 400. This grit is mostly used for final finishing before painting. It’s what you sand your car paint, or primer right before you’re ready for cleaning, tacking and painting.

Some say you can go down to 600, and you can if you wish. In my years of auto body work and paint experience, 400 is the magic number. And of course, most times you’ll be wet sanding with this paper.

Refinishing Sand Paper Grits: 1200, 1500, 2000, 2500 and 3000

These sandpaper grits are used for detailing and refinishing.You can rejuvenate older paint jobs and also use them to cut out orange peel from new spray paint jobs.

When used for color sanding and buffing, 1200 can used for your initial cut. You want to be careful when sanding with 1200 because you can sand too deep if you don’t know what you’re looking for. If you’re new to this use 1500 for your sanding, then move to 2000. Heck, you can even start with a 2000 if you wish.

Don’t worry. I’ll show you this exact process in step-by-step video and detail so you TOTALLY “get it” within the VIP training area. To learn more about how to see all of this on video, Click Here.

When you have your clear coat all sanded down and finished with 2000-2500, you’re ready for buffing. I’ll cover buffing, pads and compounds in another lesson.

But this is basically all of the automotive sandpaper that you’ll need when working on your special project. On the other hand, you only may need some of them.

I hope you learned a lot by watching this quick video above and reading this post.

I will see you in the next lesson!
